摘要:
The invention is a method for automatically recording of a digital image series that can be used for object VR by using a movable and navigable structure on which a monocular recorder unit is supported by a mechanism with many degrees of freedom for movement of the recorder unit around the object desired to be rendered in object VR, and recording images from a number of defined halt positions. The images can be reproduced, because the recorder unit records the images in a precise pre-programmed path around the object. Data are stored on the viewpoint and angle of the images in relation to a point that is defined before the image recording is initiated. The system used for recording the images can be operated by one operator, and with this system, an unprecedented precision is obtained in object VR image series of large objects without the use of rails or other visible tracking devices to guide a monocular recorder unit around the object. A dimensionally stable 3D model can be created on the basis of the object VR image series, because the viewpoints and angles of the images are known.

Mechanical support for videocameras (6), it is mainly composed by a main telescopic arm (1) or jib, that can consist in two or more elements, the telescopic arm can also rotates 360° around its axis. Two perpendicular secondary fixed jibs (3) branch off from the main arm, the secondary jibs sustain other two perpendicular little fixed jibs. Between these ulterior fixed jibs is mounted a revolving arm on which is mounted the videocamera (6). All the movements of mobile parts of the present invention are wireless controlled by a remote pan.

The crane comprising a fixed arm with a movable counterweight (29) and mounted on a pedestal, at least two movable arms (2, 3, 4) advancing telescopically from the fixed arm (1) and a rope-driving mechanism for driving the movable arms. The rope-driving mechanism of the second and next movable (3, 4) arms constitute a first (11) and a second (12) winding drum, a first (13) and a second (14) rope pulley and four sections (17, 19, 21, 23) of a substantially inextensible driving rope. The winding drums (11, 12) of the rope-driving mechanism of the specific driven movable arm (3) are fastened in swivel fashion to the movable arm (2) preceding in relation to the driven movable arm (3) . The first and the second (14) rope pulleys are fastened to the said preceding movable arm (2) close to its corresponding external and internal ends accordingly. The first section (17) of the driving rope links the first winding drum (11) with arm (1) that precedes the preceding movable arm (2) , while the second section (19) of the driving rope links the first winding drum (11) with the driven movable arm (3) . The third section (21) of the driving rope links the second winding drum (12) with the driven movable arm (3) , with the forth section (23) of the driving rope links the second winding drum (12) with the fixed arm (1) that precedes the preceding movable arm (2).

A telescoping camera crane (30) has mechanical drive (102) and camera platform leveling systems (50,104,342,260,450), allowing for water resistant or submerged operation. Telescoping sections (54,56) of the crane arm (35) are driven by a hydraulic system (100), for smooth and near silent extension and retraction movement. Camera platform leveling and stabilizing systems (50,104,342,360,450) keep the camera level. A shock and vibration isolator (540) for the camera has a vertical axis system, including a base (548), an arm (558) pivotably attached to the base, and at least one spring (566) connected to the base and to the arm. One or more dampeners (590) are connected to the base and to the arm. A horizontal axis system (610) is supported by the vertical axis system. A leveling linkage (602) connects the vertical and horizontal axis systems. The leveling linkage has adjustment features that allow for compensation of camera lens angulation caused by movement of the camera (536) supported on a vehicle (32) rolling over rough or uneven ground.
